ASST. PROFESSOR KAVYA P

2. ABSTRACT
The present study deals with the effect of stabilizers on the early strength
gain of soil stabilized with waste plastic strips.
 The development of UCC strength of stabilized soil with waste plastic strip
over a curing period of 2 hours, 3 days and 7 days was studied.
 The waste plastic strips used in the present work were made into strips of
12mm length and 3mm breadth.
 The results of the study indicated that addition of waste plastic strips
resulted in increase in early strength with different proportions (1%,
1.25%,1.5%) respectively.

3. INTRODUCTION
For the construction of any kind of structure resting on weak soil, there are many
available methods used to improve the bearing capacity and reduce the settlement of
such soils. One of these methods is using reinforcement.
 Recycling plastic waste from water bottles has become one of the major challenges
worldwide. The bottled water is the fastest growing beverage in the world.
. The plastic waste results in improvement of soil in the case of roads, buildings and
embankments, soil being a natural resource, the quantity of soil can be reduced Thus, it
provides two beneficial advantages i.e. reuse of plastic waste materials and the other is
the reduction in consumption of natural material like soil.

4. UCC TEST APPARATUS
•Compression Machine
•Proving ring of capacity 500N to 1000N with (least count 1 & 0.2 resp.)
•Dial gauge of LC 0.01
•Split mould of dia. 35mm and length 86mm
•Balance accuracy of 0.1g
•Sample extruder
•Stop watch
•Scale
•Knife
•Grease/ oil

6. PROCEDURE
•Coat the inside of split mould with a thin layer of greaseoil to prevent the adhesion of soil.
•Extrude the specimen from the sampling tube to the split mould with the help of sample
extruder and knife.
•Trim the two ends of mould.
•Weight the soil sample and mould.
•Remove the sample from the mould by splitting into two parts.
•Measure the length and dia. Of specimen.
•Place the specimen on the bottom plate of the compression machine.
•Raise the bottom plate of the machine to make contact of the specimen with the upper plate.
•Adjust the strain dial gauge and proving ring dial gauge to read zero.
•Apply the compression load by raising the bottom plate of the machine to produce the axial
strain at a rate of ½ to 2% per minute.
•Record the strain and proving dial gauge readings every 50 seconds.
•Compress the specimen till it fails or 20% of vertical deformation is reached..
